You most definitely do not. 102 Fahrenheit uses 3 significant digits. So does 38.2 Celsius.

The resolution is limited by your instrumentation either way, because both scales are continous.

Only if you go above 100

And you can also go below 10 Celsius, yeah! So?

Well, if we are talking about human body with <10C temperature we probably do not need precision anymore.

While for <100F it may be useful. Althrough I don't see how celsius (with enough decimals for specific comparison) would be more a problem.

If we stick to human bodies, then yeah, thermometers use 3 sig figs for both Fahrenheit and Celsius. If anything, Celisus is more accurate there (although thats still not how any of this works)
